The needle winding mechanism 140 is mounted on the worktable 120, and the worktable 120 can rotate relative to the frame 110 to drive the needle winding mechanism 140 to rotate relative to the frame 110. The needle winding mechanism 140 is used for inserting the pins into the pole piece sheets 200 and rotating the pole piece sheets to wind the pole piece sheets 200 and finally form the battery core. Specifically, the number of the winding needle mechanisms 140 is three, the three winding needle mechanisms 140 are arranged on the workbench 120 in an annular array manner, and the workbench 120 can drive the winding needle mechanisms 140 to switch stations, so that continuous uninterrupted production of the battery cells is facilitated, and the production efficiency is improved.
It should be noted that the needle winding mechanism 140 has a first station, a second station and a third station, and the working platform 120 can rotate relative to the frame 110, so that the three needle winding mechanisms 140 mounted on the working platform 120 can be switched continuously in position at the three stations to realize the station switching operation.

It should be noted that the cut-after feeding mechanism 130 is installed on the frame 110, and the position of the cut-after feeding mechanism 130 corresponds to the first station. The chasing and cutting feeding mechanism 130 is used for feeding the pole piece sheet 200 into the needle winding mechanism 140 when the workbench 120 drives the needle winding mechanism 140 to rotate to the first station, so as to realize the feeding action of the pole piece sheet 200. The winding needle mechanism 140 is used for winding the pole piece material 200 to realize the winding action of the battery core. The chasing and feeding mechanism 130 is further configured to chase and cut the pole piece material 200 when the pole piece material 200 wound by the winding needle mechanism 140 reaches a preset length, so as to cut the pole piece material 200 in a feeding motion state of the pole piece material 200, thereby preventing the winder 100 from stopping, and improving the production efficiency.
Specifically, in the chasing process, the chasing and cutting feed mechanism 130 is accelerated to the same speed as the feeding speed of the pole piece 200, then the chasing and cutting feed mechanism 130 clamps the pole piece 200, at this time, the pole piece 200 and the chasing and cutting feed mechanism 130 move synchronously and keep relatively static, and then the chasing and cutting feed mechanism 130 cuts the pole piece 200 to cut the pole piece 200, so as to complete the chasing and cutting action.
Further, the membrane feeding mechanism 150 is mounted on the frame 110, the position of the membrane feeding mechanism 150 corresponds to the first station, and the membrane feeding mechanism 150 is configured to feed the membrane sheet 300 into the needle winding mechanism 140 when the workbench 120 drives the needle winding mechanism 140 to rotate to the first station, so as to realize the feeding action of the membrane sheet 300. The ending rubberizing mechanism 160 is installed on the frame 110, the ending rubberizing mechanism 160 corresponds to the second station in position, and the ending rubberizing mechanism 160 is used for ending rubberizing the pole piece sheet 200 when the workbench 120 drives the winding needle mechanism 140 to rotate to the second station, so as to form a battery cell. The blanking mechanism 170 is installed on the frame 110, the position of the blanking mechanism 170 corresponds to the third station, and the blanking mechanism 170 is configured to blank the battery cell when the workbench 120 drives the needle winding mechanism 140 to rotate to the third station.

One of the top-up cutting feeding mechanisms 130 is used for feeding and top-up cutting the positive electrode sheet stock, the other top-up cutting feeding mechanism 130 is used for feeding and top-up cutting the negative electrode sheet stock, and each of the diaphragm feeding mechanisms 150 is used for feeding a layer of diaphragm sheet stock 300. Specifically, the two separator feeding mechanisms 150 and the two chasing and cutting feeding mechanisms 130 are alternately arranged so that one layer of separator sheet 300, the positive electrode sheet, one layer of separator sheet 300, and the negative electrode sheet are sequentially attached and simultaneously wound on the winding needle mechanism 140, thereby forming the battery cell.
In the working process of the cut-after feeding mechanism 130, firstly, the first winding needle mechanism 140 winds the pole piece sheet 200 at a first station; when the pole piece sheet material 200 wound by the first winding needle mechanism 140 reaches a preset length, the chasing and cutting feeding mechanism 130 is started, and the pole piece sheet material 200 is clamped and cut; after cutting, the cut part of the pole piece material 200 continues to be wound on the first winding needle mechanism 140 along with the rotation of the first winding needle mechanism 140 until winding is completed, and the rest part of the pole piece material 200 continues to move under the clamping action of the cut-after feeding mechanism 130, and meanwhile, the workbench 120 drives the three winding needle mechanisms 140 to rotate so as to enable the three winding needle mechanisms 140 to switch work stations; when the third needle winding mechanism 140 rotates to the first station, the first needle winding mechanism 140 rotates to the second station, and the chasing and cutting feed mechanism 130 just feeds the rest of the pole piece sheet 200 into the third needle winding mechanism 140, so as to realize the feeding action of the pole piece sheet 200; and circulating in this way, continuously winding the pole piece material 200 by using the three winding needle mechanisms 140 to form the battery core.
